You wanna use that as an avatar? The limit is 150x150, just so you know.
To be honest, the image isn't very suitable for such a shoop, because as you can see, Pwngoat's left eye is only partially visible and that makes it difficult to accomplish a realistic effect. However, I'm not really sure if the eyes are supposed to be visible at all (the opacity in this image is 34%). Here's a different version (opacity 100%). And yeah, the glasses are "redish" in both versions, but because of the opacity, the second image makes it more obvious.
Personally I prefer the first one, even though the effect isn't very realistic (both because of the eye and because I'm an amateur, lol).
And I couldn't resize it exactly how you wanted, but if you want it in different size, just ask.
